Description of problem:
Attempting to add a printer via samba that is attached to a Windows computer on my LAN. I can browse to find the computer, but when asked for authentication, the OK and Cancel buttons are unresponsive, and I am unable to add said printer.
My LAN is identical to when it worked in the past, the only difference is I upgraded my system from F18 to F19.

Version-Release number of selected component (if applicable):
system-config-printer-libs-1.4.1-3.fc19.noarch
system-config-printer-1.4.1-3.fc19.x86_64
system-config-printer-udev-1.4.1-3.fc19.x86_64

How reproducible:
Always

Steps to Reproduce:
1. start system-config-printer
2. select 'add'
3. select 'Windows Printer via SAMBA'
4. select 'browse'
5. Browse through WORKGROUP then computer name
6. Authentication window appears but does not function as described above.
7. I must press 'Alt-F4' to close it.

Actual results:
Unable to add samba printer

Expected results:
Ability to add samba printer
